Plant Photosynthesis Presentation Transcript

Slide 1 - PHOTOSYNTHESIS
Slide 2 - Photosynthesis Where does the energy come from that sustains all life? The Sun!! Well most of it anyway……
Slide 3 - Respiration vs. Photosynthesis Photosynthesis and respiration as complementary processes in the living world. Photosynthesis uses the energy of sunlight to produce sugars and other organic molecules. These molecules in turn serve as food. Respiration is a process that uses O2 and forms CO2 from the same carbon atoms that had been taken up as CO2 and converted into sugars by photosynthesis. In respiration, organisms obtain the energy that they need to survive. Photosynthesis preceded respiration on the earth for probably billions of years before enough O2 was released to create an atmosphere rich in oxygen. (The earth's atmosphere presently contains 20% O2.)
Slide 4 - Cellular Respiration -vs- Photosynthesis
Slide 5 - Overview of Photosynthesis 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O DG = + 686 kcal/mol Photosynthesis, like cellular respiration, is a series of redox reactions! What is being oxidized and what is being reduced in the summarizing equation above?
Slide 6 - Early thinking: O2 released came from the CO2 CO2  C + O2 C + H2O  CH2O sugar Water was added to the carbon to make sugar van Neil’s experiments with the sulfur bacteria showed that the bacteria used CO2 but did NOT release O2 ...he suggested that plants split water as a source of e- and H+ Historical perspective Scientists used radioactive isotopes to test this idea
Slide 7 - Experiment #1 H218O CO2 CO2 CO2 CO2 CO2 CO2 CO2 H2O C18O2 C18O2 C18O2 C18O2 C18O2 C18O2 C18O2 Experiment #2 18Oxygen (Heavy Oxygen) Isotope Experiment…

Slide 9 - 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O C18O2 Hypothesis: If H2O is being oxidized H218O 18O Can you predict where the heavy oxygen will end up in each case? 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O 18O 18O Isotope Experiment
Slide 10 - 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O C18O2 H218O 18O 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O 18O The Actual Results!! So..it’s the water that’s being oxidized!
Slide 11 - 6 CO2 12 H2O Reactants Products C6H12O6 6H2O 6O2 Tracking Atoms in Photosynthesis…
Slide 12 - What does this suggest about photosynthesis? 6CO2 + 12H2O  C6H12O6 + 6O2 + 6H2O The sugars that result from photosynthesis are produced by adding the hydrogen ions and electrons from water to carbon dioxide, NOT by splitting CO2 and adding water! oxidized reduced H+ and e-
Slide 13 - internal leaf structure chloroplasts outer membrane inner membrane thylakoid Plant Photosynthesis
Slide 14 - The stages of photosynthesis… Light Dependent Reactions Occurs along the thylakoid membrane this is where H2O is oxidized. chemiosmotic production of ATP! electron carrier (NADPH) is synthesized
Slide 15 - Light Independent Reactions Occurs in the stroma of the chloroplast. Where CO2 is “fixed” into sugars! The stages of photosynthesis…
Slide 16 - How plants harness energy from sunlight… Photosynthetic pigments Chlorophylls a – the “main” photosynthetic pigment Chlorophyll b Accessory pigments.. Carotenoids
Slide 17 - Photosynthetic pigments are arranged as “photosystems”
Slide 18 - What wavelengths of light do you think plants use the least in photosynthesis?
Slide 19 - Photosystems use some wavelengths of light but reflect others…
Slide 20 - Light Harvesting Pigments Reaction Center Photon Photosystem From the Photosystem, e- are passed along an Electron Transport Chain.. The Photosynthetic Electron Transport Chain (PETC)
Slide 21 - PETC Photon Photosystem
Slide 22 - Photosynthetic Electron Transfer Chain (PETC) series of electron carriers which take electrons from photosystem, and.. ultimately carry electrons to NADP+
Slide 23 - Photosystems Experiments in the 1940’s suggested that light photons are absorbed at 2 different points along the same PETC.… In fact, there are two Photosystems in operation
